I recently bought 2 2x512 DDR400 Kingston HyperX Dual Channel RAM kits. After having installed all of them, when I booted up my PC I noticed it said 1.5 gb's of ram, when I should be having 2 gb's. I let it boot on into Windows, and opened up Everest. To my surprise, each stick of RAM was detected by Everest, yet in memory it says "1.5" why?

Nah, I got the problem straightened out, I now have an Abit IC-7 that my friend gave me and it loads up the 2 GB! Works better than my previous motherboard as well. Not to mention it was a pain to remove that sticky crap that my Tt Big Typhoon left behind on my old motherboard .
